For example, each severe tropical cyclone (i.e. Category 4–5 on the Saffir-Simpson scale) crossing northeast Australia's tropical coastline since the last significant change in sea levels (about 5,000 years ago) has 'emplaced' such ridges within the coastal landscape forming, in some places, series of ridges and a geomorphological record of ...

Extratropical cyclones can also be dangerous when their low-pressure centers cause powerful winds and high seas. [120] A subtropical cyclone is a weather system that has some characteristics of a tropical cyclone and some characteristics of an extratropical cyclone. They can form in a wide band of latitudes, from the equator to 50°.
The NHC and the Central Pacific Hurricane Center assign tropical cyclone intensities in 5 knot increments, and then convert to mph and km/h with a similar rounding for other reports. So an intensity of 115 kn is rated Category 4, but the conversion to miles per hour (132.3 mph) would round down to 130 mph, making it appear to be a Category 3 storm.
A dangerous weather phenomenon called a bomb cyclone that occurs in mid-latitudes - between Earth's tropics and the polar regions - can bring strong and damaging winds, torrential rains, heavy ...
If a tropical cyclone intensify further and reaches wind speeds of 90 knots (170 km/h; 100 mph), it will be classified as an intense tropical cyclone. A very intense tropical cyclone is the highest category on the South-West Indian Ocean Tropical Cyclone scale, and has winds of over 115 knots (213 km/h; 132 mph). [24] [25]
The total is likely higher because satellite monitoring technology was not available until the 1960s and cyclones that could have been a Category 5 storm may have remained undetected.
A Category 5 Atlantic hurricane is a tropical cyclone that reaches Category 5 intensity on the Saffir–Simpson hurricane wind scale, within the Atlantic Ocean to the north of the equator. They are among the strongest tropical cyclones that can form on Earth, having 1-minute sustained wind speeds of at least 137 knots (254 km/h; 158 mph; 70 m/s).
